Measurement of the direct $CP$-violating charge asymmetry in $D_s^{\pm }\to \varphi {\pi }^{\pm }$ decays

D0 Collaboration

We present a measurement of the direct $CP$-violating charge asymmetry in $D_s^{\pm }\to \varphi {\pi }^{\pm }$ decays where the $\varphi$ meson decays to $K^{+}{K}^{-}$, using the full Run II data set with…
